Fix Y2K38: Comprehensive 2038 timestamp overflow fixes across submodules by devin-ai-integration[bot] · Pull Request #3 · arthur-cog-sonic/sonic-buildimage

Why I did it

This PR addresses the Y2K38 (Year 2038) timestamp overflow problem across multiple SONiC components. The Y2K38 problem occurs when 32-bit signed integers used to store Unix timestamps overflow on January 19, 2038 at 03:14:07 UTC (value 2147483647).

Without this fix, various SONiC components will malfunction after 2038 due to timestamp overflow in timers, authentication logs, FDB entries, and routing protocol timestamps.

How I did it

Added Y2K38 fixes across multiple components:

iccpd: Added iccp_time.h header with compile-time assertion ensuring time_t is 64-bit
sonic-frr: Added patch 0098-SONiC-ONLY-Y2K38-Add-compile-time-check-for-64-bit-time_t.patch to verify 64-bit time_t at compile time
sonic-pac: Changed authmgrAuthHistoryLogTimestampGet() parameter from uint32* to uint64*
Updated submodules with Y2K38 fixes:
- sonic-wpa-supplicant: Changed os_time_t from long to int64_t
- sonic-stp: Changed timer/timestamp types from UINT32 to UINT64
- sonic-platform-common: Added epoch extension logic for 32-bit hardware timestamps
- sonic-sairedis: Changed FDB m_timestamp from uint32_t to uint64_t
Added test suite: tests/y2k38/run_all_y2k38_tests.py to verify Y2K38 fixes

Updates since last revision

Fixed FRR patch application failure:

The FRR Y2K38 patch was failing with lib/libfrr.h: patch does not apply because the patch context didn't match FRR 10.4.1's actual file structure
Updated patch to use correct context (includes at lines 18-19: hook.h, northbound.h) instead of incorrect context (sigevent.h, vector.h)
Verified patch applies cleanly with git apply --check

Previously added:

src/iccpd/tests/test_y2k38.c: 10 tests verifying time_t size, Y2K38 boundary handling, timestamp arithmetic
src/sonic-pac/authmgr/tests/test_y2k38.c: 10 tests verifying uint64 timestamp storage
Updated tests/y2k38/run_all_y2k38_tests.py with detailed instructions for running all Y2K38 tests

How to verify it

Run the Y2K38 integration test suite:

python3 tests/y2k38/run_all_y2k38_tests.py

Run individual component tests (requires build environment):

# iccpd
cd src/iccpd/tests && gcc -I../include -o test_y2k38 test_y2k38.c && ./test_y2k38

# sonic-pac
cd src/sonic-pac/authmgr/tests && gcc -o test_y2k38 test_y2k38.c && ./test_y2k38

# sonic-sairedis
cd src/sonic-sairedis && make check

Build the image and verify compile-time assertions pass
Review the linked submodule PRs for detailed changes

Review Checklist for Human

FRR patch application: ~~Verify patch applies cleanly~~ Fixed - patch context updated to match FRR 10.4.1
sonic-pac API callers: Search for all callers of authmgrAuthHistoryLogTimestampGet() and verify they handle uint64* correctly
32-bit build impact: The _Static_assert(sizeof(time_t) >= 8) will fail on 32-bit systems - confirm this is acceptable
New test files compile: Verify src/iccpd/tests/test_y2k38.c and src/sonic-pac/authmgr/tests/test_y2k38.c compile without errors
Submodule PRs: Review the individual submodule PRs for completeness:
- sonic-wpa-supplicant: Fix Y2K38: Change os_time_t to 64-bit and add tests sonic-wpa-supplicant#1
- sonic-stp: Fix Y2K38: Change timer and timestamp types from 32-bit to 64-bit sonic-stp#1
- sonic-platform-common: Fix Y2K38: Add epoch extension logic for 32-bit hardware timestamps sonic-platform-common#2
- sonic-sairedis: Fix Y2K38: Change FDB timestamp from uint32_t to uint64_t sonic-sairedis#2

This commit addresses the Y2K38 (2038 timestamp overflow) issue by adding compile-time assertions to ensure the system is using 64-bit time_t. Changes: - Added include/iccp_time.h with: - _Static_assert to verify sizeof(time_t) >= 8 - Y2K38 boundary constants - Helper functions for Y2K38-safe time operations - Updated include/iccp_csm.h to include the new iccp_time.h header The CSM struct uses time_t for several timestamp fields (connTimePrev, heartbeat_send_time, heartbeat_update_time, peer_warm_reboot_time, etc.). On 64-bit Linux systems, time_t is already 64-bit. This change adds compile-time verification to catch any 32-bit builds that would be vulnerable to Y2K38 overflow. Co-Authored-By: Arthur Poon <arthur.poon@windsurf.com>

This commit addresses the Y2K38 (2038 timestamp overflow) issue by changing the auth history timestamp parameter from 32-bit to 64-bit. Changes: - authmgr/common/auth_mgr_api.h: Changed authmgrAuthHistoryLogTimestampGet() pTimeStamp parameter from uint32* to uint64* This ensures that authentication history timestamps can correctly represent dates beyond January 19, 2038. Co-Authored-By: Arthur Poon <arthur.poon@windsurf.com>

This commit addresses the Y2K38 (2038 timestamp overflow) issue by adding a compile-time assertion to verify that time_t is at least 64-bit. Changes: - Added patch/0098-SONiC-ONLY-Y2K38-Add-compile-time-check-for-64-bit-time_t.patch - Updated patch/series to include the new patch FRR uses time_t extensively for timestamps in routing protocols (BGP, ISIS, OSPF, etc.). This compile-time check ensures that FRR is built on a system with 64-bit time_t support, preventing timestamp overflow on January 19, 2038. Co-Authored-By: Arthur Poon <arthur.poon@windsurf.com>

This commit adds a comprehensive test suite to verify Y2K38 fixes across all sonic-buildimage submodules. Tests include: - Compile-time checks for 64-bit time_t - Timestamp arithmetic beyond 2038 boundary - Epoch extension logic for 32-bit hardware timestamps - Submodule-specific tests verifying Y2K38 fixes are in place Run with: python3 tests/y2k38/run_all_y2k38_tests.py Co-Authored-By: Arthur Poon <arthur.poon@windsurf.com>

Updated submodules to include Y2K38 (2038 timestamp overflow) fixes: - sonic-wpa-supplicant: Changed os_time_t to 64-bit - sonic-stp: Changed timer and timestamp types to 64-bit - sonic-platform-common: Added epoch extension logic for 32-bit hardware timestamps - sonic-sairedis: Changed FDB timestamp to 64-bit Co-Authored-By: Arthur Poon <arthur.poon@windsurf.com>
